Fixes #1408 The wl_* types are required in multiple libraries which in turn seem to have a circular dependency that Platform.IO has issues with in certain modes. Avoid the issue by moving the common headers into the core directories so they will be accessible by all libs. Move StackThunk to core directory, too
